Just a few days before Christmas, a rather fluish Santa Claus is going through his mailbag, and he finds a letter from a lad called Rascal. But who is Rascal and why was the letter post marked 50 years ago? No sooner has this happened, when a strange sound rings out several times rum-tum-tum. It is heard again and again. Every time the sound rings out, some little accident happens to Santa. Nothing too serious, but someone is clearly trying to tease the old man.
